Darina [25.2K]

Answer:

The correct answer is: It allows large masses of food to pass through the esophagus when swallowing.

Explanation:

The trachea, or windpipe, is a hollow organ that <u>connects the larynx to the bronchi and allows the passage of air</u> so it can reach the lungs and make the gas exchange possible.

The trachea has cartilages around it to reinforce the tube for protection and to maintain the airway open. The places where there's cartilage are the anterior and the lateral sides of the trachea. This cartilage has the shape of an incomplete ring, or the shape of a C to allow the passage of food. The side that has no cartilage is the posterior side of the trachea, which is the side that is <u>in relation to the esophagus</u> - the part of the gastrointestinal tract that transports the food from the buccal cavity to the stomach.
